hololive talents have spoken out against users submitting AI generated fanart to their art tags. A new image generator, available since October 3, has been able to output images that are difficult to differentiate from original fan art at a glance.
Takanashi Kiara and Mori Calliope have voiced their preference for original art. While the validity of AI art is a contentious topic, the talents are in their right to request their hashtags to be used for their intended purpose.
Haachama shared a piece of AI generated fanart that she has since taken down.

Developments in NovelAI allow users to generate images with an engine trained via third party anime fanart databases. Users have found it more effective at generating anime style images compared to DALLE2 and other engines that made a splash a few months ago. At a glance, some of these images are difficult to differentiate from hand drawn art, particularly when you are just scrolling through your feed.
On closer inspection, details such as hands and feet are often portrayed incorrectly by the software, which fans are using to recognise which images are computer generated.
The above images serve as examples of AI generated art and have been sourced via reddit.com [1], [2].
Commonly used image generators include NovelAI and Waifu Diffusion, both of which are built on the AI Stable Diffusion and have been trained using Danbooru. Danbooru is a third party database of reuploaded fanart. Its uploading rules do not specify that permission from the original artist is required.
Danbooru released a statement urging artists to contact NovelAI directly if they do not wish their art to be used to train the AI.
Since the technology is still new, artists have not yet been able to react by sending explicit requests or update their licensing terms to disallow their work to be used to train the AI.
NovelAI offers a subscription service and sells premium currency called “Anlas,” which is required to generate anime style images.
Both hololive’s and NIJISANJI’s fan work guidelines request that derivative works do not infringe or violate the rights of a third party.
Fan work policies grant the agencies permission to use art depicting their talents for thumbnails and other assets. There are concerns that talents may be breaching copyright laws when unsuspectingly using AI-generated images for official purposes.
